Gas Operated

Specialized Tactical System's line of Direct Impingment rifles were developed due to the call from overseas operators trying to cut weight out of their kit. Despite current "armchair warrior" and "Online Call of Duty Operators" opinions, DI guns are not horrible, but offer distinct advantages and dissadvantages when compared to piston weapons. Two of the main advantages of DI guns is cost and wieght, both are substantailly less than a piston driven weapon. STS DI Rifles are built to capitalize upon both of these advantages.
